CDC 1631F-E
16-Bit Automotive CAN Controller
The CDC 1631F-E is a pin-compatible
mask ROM derivative of Micronas’ 16-bit
Car Dashboard Controller family based on a
WDC 65C816 CPU core.
Features
The CDC 16xyF offers 2 Kbytes of RAM
and 64 Kbytes of ROM. The device can be
operated with an external quartz, at clock
frequencies from 4 to 12 MHz. Communication is possible via one FullCAN module
according to Bosch specification V2.0B.
Only one single 5 V power supply is
needed. Two low-power modes are available to reduce power consumption significantly.
◆ Three CPU operation modes
(Fast, Slow, Deep Slow)
The device also contains the patented builtin ERM (EMI Reduction Module).
◆ 64 Kbytes mask ROM
◆ 2 Kbytes SRAM
◆ Two low-power modes
(Idle and Wake)
◆ RTC delivering hours, minutes, seconds
◆ Polling/Flash timer output
◆ 4- to 12-MHz oscillator
◆ EMI reduction module (ERM)
◆ One comparator
◆ 48 × 4 LCD module
◆ One UART
◆ One SPI
◆ One CAN module with 256 bytes of
object RAM according to Bosch specification V2.0B (16 message objects)
◆ Five stepper motor drivers
◆ Three PWM modules
◆ Sound generator with auto decay
◆ Two SW-selectable clock outputs
◆ Digital watchdog
◆ 16-bit free-running counter with three
capture/compare modules
◆ Central clock divider
◆ Patch module (up to 5 cells)
◆ Interrupt controller with 16 inputs and
16 priority levels
◆ 1 ×16-bit timer and 2 ×8-bit timer
◆ Four port interrupts
◆ Regulator input supervision for reset/
alarm (alarm comparator)
◆ Clock and supply supervision
◆ 9-channel 10-bit ADC
◆ −40 to +105 °C case temperature range

System Architecture
The
Car
Dashboard
Controller
CDC 1631F-E contains a WDC 65C816
processor which operates at a maximum
clock frequency of 12 MHz. An internal RC
oscillator can provide an alternative clock
signal to the RTC during power saving
modes.
